Zero Install is a decentralised installation system. Meta-data about each
package is published in a "feed" file. The Zero Install client reads these feeds
files and downloads and runs the programs. The feed files can be created
manually (e.g. using 0publish or 0publish-gui). However, Debian and RPM packages already
contain much of the required information. This program extracts the information
in an existing package and uses it to generate the feed.
